The Onboard Knock Module (OKM) is fitted onto the board of a Plug-In ECU prior to delivery and linked to the knock sensor.

The module is preconfigured to suit the standard vehicle. If the vehicle is modified significantly, contact an authorised MoTeC dealer for further advice. The OKM requires a competent tuner to tune the knock control system. This is highly specialised work and therefore the MoTeC Knock Modules will only be available through authorised dealers that have undertaken specific training.
